ESPHome Nuki Lock Component (ESP32)

This module brings seamless integration of Nuki Smartlocks into ESPHome, creating a rich Home Assistant lock platform with 24 entities.

The lock entity updates whenever the lock's state changes - whether through the Nuki app, Home Assistant, or manually. This is achieved via the efficient Nuki BLE advertisement mechanism, ensuring your lock status is always up-to-date.

    on_paired_action:
      - lambda: ESP_LOGI("nuki_lock", "Paired sucessfuly");

After running ESPHome (esphome run <yamlfile.yaml>), follow these steps to pair your Nuki Smartlock:

1. Activate Pairing Mode: Enable pairing mode on the ESPHome component. You can do this by toggling the Pairing Mode switch entity in Home Assistant or by triggering the nuki_lock.set_pairing_mode action in an automation.

2. Set Nuki to Pairing Mode: On your Nuki Smart Lock, press and hold the button for 5 seconds until the LED lights up to enter pairing mode.

3. Complete Pairing: Once paired, the ESPHome entities will automatically update with the current lock status, and pairing mode will turn off.

Your Nuki Smartlock is now connected and ready to use!

on_...:
  - nuki_lock.set_pairing_mode:
      pairing_mode: True

Action: Unpair

To unpair your Nuki Smart Lock, use the following action:

Callbacks

To run specific actions when certain events occur, you can use the following callbacks:

on_pairing_mode_on_action:
  - lambda: ESP_LOGI("nuki_lock", "Pairing mode turned on");
on_pairing_mode_off_action:
  - lambda: ESP_LOGI("nuki_lock", "Pairing mode turned off");
on_paired_action:
  - lambda: ESP_LOGI("nuki_lock", "Paired sucessfuly");

Events

By default, this component sends Nuki logs as events to Home Assistant, enabling you to use them in automations.

• To Disable Logs: Set the event property in your YAML configuration to none if you don't want to receive log events.

• To View Log Events: Go to Home Assistant Developer Tools -> Events, and listen for esphome.nuki events to monitor log activity.

These log events provide insights into lock operations and help fine-tune automations based on real-time lock data.
